Barcelona, Spain: The average number of moderate or marked side-effects reported by breast cancer patients is lower if they are treated with radiotherapy to part of the breast or a reduced dose to the whole breast, rather than with standard radiotherapy to the whole breast, according to new findings presented at the 11th European Breast Cancer Conference on Friday.
The IMPORT LOW study of 2016 women in 41 centres in the UK has already shown that partial breast and reduced dose radiotherapy was as effective as whole breast radiotherapy in controlling the cancer at five years, and women in the partial breast and reduced dose groups reported fewer side-effects, including less change in the appearance of the breast.
These latest results, which focus predominantly on side-effects affecting the breast and also body image reported during the five years following radiotherapy, show that over half of patients in the study did not report moderate or marked side-effects at any point and that most side-effects reduced over time. The number of side-effects reported per person were fewer in the partial breast and reduced dose groups compared with the whole breast radiotherapy group.
